Description
The invention relates to a kind of super capacitance degaussing machine for ship, is the method that adopts super capacitor energy-storage, has reduced on-the-spot real-time power supply capacity, is mainly used in the warship demagnetization.Belong to military equipment.
Existing warship all adopts on-the-spot real-time power supply with degausser, through after the rectification with current constant mode to being wrapped in anti-magnetized coil provider on the warship body to alternate and the programmable current that progressively successively decreases, its capacity as required voltage from tens to the hundreds of volt, electric current is trained from tens to several Wan An, instantaneous power reaches MW class, bigger to the field power supply demand power, give and use and bring wartime a lot of inconvenience.
The present invention provides a kind of method that adopts super capacitor energy-storage, by give the super capacitor electric energy supplement with the working clearance in advance, provides electric energy with field power supply to anti-magnetized coil by super capacitor, reaches and reduces on-the-spot realtime power purpose.
Fig. 1 is its electrical schematic diagram.It is by isolating transformer TB, transformer state detection and control unit TBCE, constant current unit POW, constant current detection and control unit POCE, super capacitor group unit CAP, the detection of super capacitor group and control unit CAPCE, electric current current of commutation control unit IGBTS, IBGT drive detection and ten element circuits such as control unit IGBTCE, control unit CTR and computer C 0 MP are formed.
Its operation principle is: by transformer station or the next AC power of generator, send into isolating transformer TB, export to constant current unit POW, the suitable voltage and current of this unit output is connected in parallel on the super capacitor unit CAP, the H bridge unit IGBTS that is made of IGBT again, the commutation of realization output current, with the mode Control current size of copped wave, export to anti-magnetized coil simultaneously, reach the purpose of warship body demagnetization.
Control unit CTR controls the operating state of each unit as required respectively with workflow, also the state of each unit is protected and monitored.Control unit CTR joins by RS485 interface and industrial control computer COMP.Control unit is controlled and is monitored each unit in the circuit, guarantees the safe operation of complete equipment, by the state of RS485 interface with each unit and the whole series, shows on industrial control computer COMP simultaneously.Industrial computer also will be to generator POWER monitoring in real time and control.
Fig. 2 is the loop of power circuit of a specific implementation circuit of the present invention.Expression constant-current circuit unit in the HENYALIU frame, it is typical controllable silicon constant-current circuit, is made up of controllable silicon, triggering and control circuit.C1 and C2 represent the super capacitor group, by many super capacitor connection in series-parallel, reach rated voltage and rated capacitance, satisfy the energy storage requirement.The H bridge is made up of IGBT1, IGBT2, IGBT3, IGBT4, DE1, DE2, DE3 and DE4, and the H bridge is realized the commutation and the control output current size of output current, and L1 is the afterflow inductance.Constant current HENYALIU unit is connected with H bridge unit through diode D1.
For obtaining bigger output current, in the super capacitance degaussing machine for ship of reality, output is to be formed in parallel by several same H bridges, and each H bridge is connected with constant current HENYALIU unit by diode, and diode can be isolated carrying out the loop between each H bridge.Each H bridge output is by the big electric current of inductance L output in parallel again of output serial connection.
Control unit CTR is a control chip with the DSP of American TI Company 320 series, measures monitoring unit circuit TBCE by isolating transformer, and isolating transformer TB is measured, controls and protection; Measure monitoring unit POCE by constant current, constant current unit POW is measured, controls and protection; Measure monitoring unit CAPCE by super capacitor, super capacitor unit CAP is measured, controls and protection; Measure and monitoring unit IGBTCE by the H bridge, the H bridge unit that IGBT constitutes is measured, controlled and protection.
Four IGBT pipes of control H bridge, the positive and negative pulse that replaces that output duration is adjustable; With chopping way, the size of control impuls output current; It is adjustable that each exports interpulse blanking time; By controlling the operating time successively of each H bridge, control the time of the rising edge and the trailing edge of total output current, reduce the di/dt of total output current, the power device safety of protection super capacitance degaussing machine.
Utilizing super capacitor can reduce on-the-spot realtime power, is example with 600 volts of 4000 amperes of demagnetization power supplys commonly used now, does not adopt the existing product of super capacitor, its on-the-spot 2400 kw of power that need.If adopt the super capacitor scheme, the output positive negative pulse stuffing duration is 4～7 seconds, be 9～17 seconds blanking time, each pulsion phase reduces by 9～19% to previous pulse, the total number of pulse is 60, then adopt rational super capacity, on-the-spot 1/3～1/5 of the former power that only needs is 800～480 kilowatts.Utilize the blanking time of preceding 30 minutes of demagnetization and output pulse that super capacitor is charged, can realize exporting the repeatedly circulation of pulse.
Another concrete application of the present invention is the capacity that increases super capacitor, directly utilize the generator of warship self, small-power is for a long time to super capacitor charging energy storage, further reduce the realtime power demand, export big electric current to warship self demagnetization, this has just constituted and has been exclusively used in carrier-borne degausser, can be used for warship and submarine.
Super capacitance degaussing machine that the present invention relates to and carrier-borne degausser militarily have very important strategic importance.
